In the interview on "Fox News Sunday," Trump also said he won't have "anything to do with the management" of his company. But he suggested three of his adult children would play a large role in his businesses — something some experts have said would not address problems with conflicts.

"My executives will run it with my children. It's a big company, it's a great company. But I'm going to have nothing to do with management," Trump said. "When I ran, everybody knew that I was a very big owner of real estate all over the world."

Trump is expected to hold a news conference on Thursday and give details about how he plans to separate himself from his businesses.

Although federal law doesn't require Trump to divest or sell what he owns, many experts say Trump has an ethical obligation to give up business interests that could factor into how he makes decisions as president.

Some government officials appear to think full divestiture is Trump's best decision, too. Last month, the Office of Government Ethics sent a burst of tweets cheering Trump should he fully divest his businesses.

The tweets, sent after Trump announced his forthcoming press conference, said the "only way to resolve these conflicts of interest is to divest."

The ethics office examines the financial disclosures of executive branch officials and works with them to avoid conflicts between their business holdings and their public responsibility.
